...Deanne van Rooyen; Sandra M. Barr; Chris E. White; James L. Crowley The Bras d’Or terrane of central Cape Breton Island, Nova Scotia, Canada, contains a well-preserved record of the Ediacaran to early Cambrian evolution of Ganderia, a Gondwana-derived terrane in the northern Appalachian orogen...

... and Baltica led to a diachronous collision with the Ganderian arc. Strike-slip slivering produced a complex transfer of terranes to both: Carolinia and smaller terranes to Ganderia, and East Avalonia to West Avalonia. The Rheic Ocean opened diachronously at c. 500 Ma, following a plate reorganization and re...

... that has not been recognized within Ganderia in the Appalachian sector of the orogen. † tobi.fritschle@gmx.de The contact between the Ribband Group and the overlying Duncannon Group has been interpreted as an angular unconformity ( Brenchley et al., 1970 ) and was also proposed to mark a terrane...

...Dawn A. Kellett; Neil Rogers; Vicki McNicoll; Andrew Kerr; Cees van Staal Abstract Devonian and younger plutonic suites of the Appalachian orogen in Newfoundland form a curvilinear belt straddling the boundary between Ganderia and Avalonia, and exhibit a general pattern of younging to the southeast...

... zircon. These characteristics are shared with the Monian terrane of Anglesey and with Ganderia in the Appalachians, indicating probable derivation from Amazonia in West Gondwana. Silurian sandstones from the Lake District show an influx of Laurentia-derived zircon, and lack the peri-Gondwanan signal...

... the transfer of Ganderia and Avalonia from Gondwana to Laurentia, which led to closure of the Iapetus Ocean and opening of the Rheic Ocean. Ganderia, a long-lived arc terrane, separated from the paleo-Caribbean margin of Amazonia at 505 Ma with a latitudinal speed of ∼9 cm/a northward, initiating the Rheic...

... on the leading edge of Ganderia, a peri-Gondwanan microcontinent. Although the Penobscot and Victoria stages of arc-backarc development occurred in a predominantly extensional suprasubduction-zone setting, they each display a distinctly different character of magmatism and sedimentation. These stages...

...Klaus J. Schulz; David B. Stewart; Robert D. Tucker; Jeffrey C. Pollock; Robert A. Ayuso Abstract The Ellsworth terrane is one of a number of fault-bounded blocks that occur along the eastern margin of Ganderia, the western-most of the peri-Gondwanan domains in the northern Appalachians that were...
